Abstract
A support for treads of a staircase is formed by a plurality of support elements each comprising an upper plate and a lower plate, the lower and upper plates of each element being adapted to rest on the upper and lower plates respectively of contiguous elements. Adjustment and fixing members enable the upper plate to be moved relative to the lower plate of each element and be fixed together. The upper plate of each element is formed with at least one pair of holes, and at least one pair of female threads is fixed to the plate, each thread being coaxial with one of the holes. The lower plate of each element is formed with a through-hole and through-slot into which are inserted two screw members, each of which also passes through one of the holes in the upper plate of the contiguous element and is screwed into the corresponding female thread in the contiguous element so as to fix these two elements together.
